Once the car system (especially in a closed ecosystem) undergoes a major version upgrade, its bootloader is usually locked, preventing downgrades. If this happens, there is basically no solution in an overseas environment. Therefore, we strongly warn: do not blindly insert a USB drive to upgrade while offline.

All vehicles on the lift must be inspected. We will provide high-definition close-up photos of the chassis directly below, suspension components, and the mid to rear section of the exhaust. We will honestly show any minor surface rust (a common phenomenon in cast iron); if we find bent longitudinal beams or extensive through-corrosion, the vehicle will be scrapped and not exported.

It usually refers to very small stone chips on the hood from high-speed driving, nail scratches on the inside of door handles, slight curb scratches on the edges of wheels, and minor wear on interior plastic parts. These do not affect the vehicle's functionality or corrosion resistance.
